Summer Math
Completed Algebra IA
Instructions: Please complete the following problems showing all work. If you use scratch paper to
work the problems out, please number the problems on the paper so that the work can be easily
associated with a problem. This packet is due on the first day of school and will count as your first daily
grade of the semester. This will be a completion grade. Full credit will not be given if work is not shown
where applicable. Once your Summer Work is graded for completion, you will have the opportunity to
review the packet with your teacher. Your first quiz of the semester will cover the topics in this packet.
If you are unclear as to solving a problem, then you are welcome to check www.coolmath.com as a
resource or www.Khanacademy.org for short videos which will explain the process. There are many
other web resources, but those are two that have proven to be excellent. You should work through the
problems until the correct solution is found, being sure to show all of the correct work along with this
solution.
